VC界面开发

1.让控件随着窗口的大小变化而变化

    重载OnSize函数：

// TODO: 在此处添加消息处理程序代码if(nType==SIZE_RESTORED || nType==SIZE_MAXIMIZED) //窗体大小发生变动。处理函数resize  {      float fsp[2]; //用于分别记录窗口发生变化的长宽新旧比  POINT Newp; //获取现在对话框的大小  CRect recta;    GetClientRect(&recta);     //取客户区大小  Newp.x=recta.right-recta.left;  Newp.y=recta.bottom-recta.top;  fsp[0]=(float)Newp.x/oldPoint.x;  //计算长度的新旧比  fsp[1]=(float)Newp.y/oldPoint.y;  //计算高度的新旧比  CRect Rect;  int woc;  CPoint OldTLPoint,TLPoint; //左上角  CPoint OldBRPoint,BRPoint; //右下角  HWND  hwndChild=::GetWindow(m_hWnd,GW_CHILD);  //取得第一个控件的句柄,用于遍历所有控件  while(hwndChild)    {     woc=::GetDlgCtrlID(hwndChild);//取得ID   GetDlgItem(woc)->GetWindowRect(Rect); //获得相对于屏幕左上角的坐标   ScreenToClient(Rect); //将屏幕坐标转换成相对客户窗口左上角的坐标   OldTLPoint = Rect.TopLeft();    TLPoint.x = long(OldTLPoint.x*fsp[0]); //用比例得出左上角的x坐标   TLPoint.y = long(OldTLPoint.y*fsp[1]); //用比例得出左上角的y坐标   OldBRPoint = Rect.BottomRight();   BRPoint.x = long(OldBRPoint.x *fsp[0]); //用比例得出右下角的x坐标   BRPoint.y = long(OldBRPoint.y *fsp[1]); //用比例得出右下角的y坐标   Rect.SetRect(TLPoint,BRPoint); //设置最新的Rect   GetDlgItem(woc)->MoveWindow(Rect,TRUE);   hwndChild=::GetWindow(hwndChild, GW_HWNDNEXT);  //获得下一个控件的句柄  }  oldPoint=Newp;}

2.为Static控件加载图片

CBitmap bm1;bm1.LoadBitmap(IDB_BACKGROUND);BITMAP structBm1;bm1.GetBitmap(&structBm1);HBITMAP   hBitmap=::LoadBitmap(AfxGetApp()-> m_hInstance,MAKEINTRESOURCE(IDB_BACKGROUND));   m_StaticTop.ModifyStyle(0,SS_BITMAP|SS_REALSIZEIMAGE);   m_StaticTop.SetBitmap(hBitmap);m_StaticTop.MoveWindow(0,0,dlgWidth,structBm1.bmHeight);

3.点击dialog任意位置，都可移动dialog

   重载OnLButtonDown函数：

void CInterfaceDlg::OnLButtonDown(UINT nFlags, CPoint point) {// TODO: Add your message handler code here and/or call defaultPostMessage(WM_NCLBUTTONDOWN,HTCAPTION,MAKELPARAM(point.x, point.y));//向系统发送HTCAPTION消息，让系统以为鼠标点在标题栏上CDialog::OnLButtonDown(nFlags, point);}

4.为dialog添加背景图片

    重载OnPaint函数：

else{//CDialog::OnPaint();CPaintDC dc(this);CBitmap m_bmpBackground;m_bmpBackground.LoadBitmap(IDB_BACKGROUND);CRect rect;GetClientRect(&rect);CDC dcMem; dcMem.CreateCompatibleDC(&dc); BITMAP bitMap;m_bmpBackground.GetBitmap(&bitMap);CBitmap *pbmpOld=dcMem.SelectObject(&m_bmpBackground);dc.StretchBlt(0,0,rect.Width(),rect.Height(),&dcMem,0,0,bitMap.bmWidth,bitMap.bmHeight,SRCCOPY);//dc.BitBlt(0,0,rect.Width(),rect.Height(),&dcMem,0,0,SRCCOPY);}

5.设置控件的背景颜色和字体颜色

    重载OnCtlColor函数：

HBRUSH CRecNineDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor){if (pWnd->GetDlgCtrlID()==IDC_BACKTOP)  {HBRUSH brush = CreateSolidBrush(RGB(200,200,200));pDC->SetTextColor(RGB(60,60,60));pDC->SetBkMode(TRANSPARENT);//pDC->SetBkColor(RGB(255,0,0));return brush;} return CDialogEx::OnCtlColor(pDC, pWnd, nCtlColor);}
